Hi guys, i got a crash, could someone help? --- queries: set histogram_size=255,histogram_type=SINGLE_PREC_HB; ANALYZE TABLE 19_org.estoque_itens PERSISTENT FOR ALL; /* Erro SQL (2013): Lost connection to MySQL server during query */ --- log: 150623 12:31:47 [ERROR] mysqld got signal 11 ; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. To report this bug, see http://kb.askmonty.org/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.
